It's only for the Chevrolet Volt and Nissan Leaf

Bosch is giving electric vehicle (EV) drivers a wireless charging option, and even new financing plans to help them afford it. 

Bosch Automotive Service Solutions teamed up with Evatran Group Inc. to offer a Level 2 240-volt wireless charging unit. It's only compatible with the Chevrolet Volt and Nissan Leaf for now, but will open up to other models later. 

Bosch recently announced its wired charging system, Power Max home charging. It only costs $449 while the new wireless system costs a whopping $3,000 -- but Bosch believes that convenience will be key to sales of the expensive wireless option.

“The main reason is convenience,” Kevin Mull, vice president of business development at Bosch Automotive Service Solutions told PluginCars. “We think this is a very viable future technology and over time, with advancements in technology, the price will start to come down.”

To help EV drivers who want the wired or wireless system, but can't afford it, Bosch is offering financing options. Option #1 includes $0 down with no monthly payments for 12 months if repaid in full in a year for charging stations that cost $1,000 or more. Option #2 offers $0 down and a five-year 2.99 percent loan on charging stations of $3,500 or more (including installation).

But that's a pretty steep price for convenience. If it takes 10s per day to plug/unplug your car, then in 10 years you'll have spent ~10 hours on this inconvenient task. Not sure how many people think that's worth $3k.

OTOH, forgetting to plug in once or twice a year is something that's worth preventing. I know first hand that running out of gas is both embarassing and wastes a lot of time.

Well the main unit is $500 so it's only a $2,500 difference. Hard to put a value on convenience. I've seen people waste a lot more money on things far more worthless.

You forget that Wireless charging is also incredibly inefficient, if you live in an area where electricity is expensive then it might add a massive amount to the cost over a few years.

It's not "incredibly inefficient" unless it's poorly designed. You can easily get 90%+ efficiency with wireless power transfer.

The wired cost of electricity for an EV will be around $400/yr. Even 20% wastage is small potatoes next to the purchase cost.

A lot of standby power there is >20% waste though. Try up to 100% compared to just switching the appliance off. Yes, it's borderline nanny state behavior, but it's worth pursuing to cut household costs over the long haul. The manufacturers are simply being stupid about standby power consumption. The nanny can be right sometimes (the laws of probability, if nothing else, demands it).

I would pay for it. Why? because it's not just the 15 secs i have to spend plugging it in. You have to unplug it also. Sometimes, i will forget if I'm in a rush in the morning. Well, I'm always in a rush in the morning.

It makes more sense for public charging stations than in-home garage ones. No futzing around with cords and stuff outside plus fewer moving parts, less chance of vandalism and so on. Just have a payment kiosk if you want to charge up.

But these need to be like 99%+ efficient to be 'green'...if too much of the power is wasted then it partly defeats the purpose of 'efficient' electric vehicles.

Reposted from previous articles on this topic, since it's important:

Loss on field-induction charging is about 10%. 10% is pretty huge, especially when taking into account the apparent size of the target population.

And especially granted the state of our power grid, which already loses a lot to the environment, and is already overtaxed...adding additional waste is a really stupid idea.

Let's make up some numbers.

There's ~8 million people in NYC. Let's say that, on average, they live 2 people to a household. Then let's say that half of those households have cars. Then let's say half of those would have an electric vehicle such as this. That's 1 million electric cars if you've managed to follow the arithmetic.

Let's say that it costs $50 a month to charge said vehicle. That's $50 million dollars a month spent just in NYC on electricity for these cars.

...and at a loss rate of 10%, that means that 5 million dollars' worth of electricity was just flushed down the toilet in a month. $60 million a year - wasted. Generated, transported, delivered...and thrown away.

Just in one city.

That seem like a good idea to you?

Change the numbers around all you want, if you don't think that $50 a month is a good number, or if you think 10% is too high, or whatever. Kind of doesn't matter. Even if it was 1% - that's still $6 million a year that got thrown in the trash.

Plug your damn car in.

I could go on and on but the point is pretty obvious. I wouldn't pay 2.5K just to avoid plugging in my car twice a day but I see no problem with those people who wish to.

On a side note I find it somewhat entertaining that someone with such poor impulse control and confidence in his argument is calling me irrepressible.

Who the frig cares?

You want to whine about inefficiency, look at the power supplies on your electronic equipment. The average desktop computer has a 15-25% power conversion loss pulling power from the wall (80 PLUS Bronze - 80 PLUS Platinum drops that down to just under 10%). The Average Dell, HP or Lenovo will be in the bronze range to reduce manufacturing costs. Hell, the charger for your laptop is about 10% power loss. How many people use computers for home and business? Compared to plug-in cars?

Personally I think 10% loss is pretty damn good for inductive power transfer. It is a hell of a lot better than what I listed just above. If I were driving an electric car, I would be all over this. Something that will save me the hassle of remembering to plug in my car? I park it at night in the middle of a huge rainstorm or blizzard, and sure as shit stinks the last thing I want to do is futz around plugging in the damn car! Just park the car in my driveway and it handles the charging business? Hell yeah! Sign me up baby!

Regardless, the "may as well do this wasteful thing since some other thing is wasteful too" argument is patently idiotic to start with.

So what if your PC isn't 100% efficient? That's not justification to waste *more* energy. Imagine if Congress passed a new budget that had a bigger deficit than the one we already have - "hey, we're already spending more than we have, so why not spend a little more?"

That's basically the argument you're making.

Also, PCs serve an important societal purpose. Saving 2 seconds because you didn't have to put a plug in a socket serves no purpose at all.

Who cares? Anyone with at least half a brain to their person, I should think.

By the way, your comparison isn't even valid in the first place. While desktop computers may have so-so efficient power supplies, at least they DO something with that power (run the computer, even if some of it is lost in the process), this is just electricity going up in smoke for no reason whatsoever. If put in the term of your silly comparison, it'd be like the power cord to your desktop computer burning off 10% of every watt going through it as heat, for no reason.

You don't need a wireless charger for your electric car. Don't be a ridiculous moron. In fact, you don't need a wireless charger for anything, it's a complete waste in every way.

You really aren't the sharpest tool in the shed are you there Flash.

Are you actually sitting there and trying to tell me that the computer you are writing your garbage on is 100% energy efficient? OMFG, Are you really that stupid? Don't have kids and you might qualify for a Darwin award when you die.

Let's try this another way since you don't seem to grasp the concept of energy efficiency.

How do you wash your clothes? Do you use a washing machine or do you take them down to the stream and beat them on a rock? You know, the latter is 100% energy efficient. Do you put your wet clothes in a dryer or are you hanging them up on a clothes line? Tell us which one wastes more energy. After all you con do both things in other ways that use none of the planet's resources. Taken that way both are a 100% waste of energy - not 10%... 100% .

So, are the folks who use washing machines or dryers morons because they are wasting energy? According to your faulty reasoning, they most certainly are.

Summary: You don't need a washing machine to wash your clothes. In fact you don't need a washing machine for anything - it is a complete waste in every way.

But which is more convenient (big tip here - take a note of this magic word)? People have been known to pay huge amounts of money in the name of convenience even if it means wasting energy.

Sure, wireless charging is less energy efficient than plugging in with a wire. So what? It is more convenient than remembering to plug in whenever you park. So is using a washing machine or a clothes dryer more convenient than their energy-friendly alternatives. People will determine if the convenience of a product outweighs the alternative methods of doing the same things even if there is a trade-off in energy consumption.

Here's more proof of why people like you are f%tards who really should just be deported before you do more damage to our society...

The fact that you clueless children keep bringing up washing machines and driers is utterly retarded. Washing machines and driers aren't simply "conveniences" similar to the a$s-smackingly profound apathy and laziness that would be required to use field-induction charging for you car instead of spending 2 seconds to plug it in.

Washing machines and driers, along with other relatively modern appliances, helped to double our available workforce. Before then, one household member (stereotypically the mother) would have to simply be at home all the time doing nothing but "housekeeping." Before the clothes washer and drier, wives would spend hours a day just on cleaning clothes. Having a washing machine and a drier meant that *hours* a day could be spent on something else...and eventually, with enough modern appliances, it became possible for women to enter the workforce and not be chained the household like a domestic slave.

And now you raging dipsh1ts are trying to compare wasting a billion dollars' worth of electricity a year by using field induction charging to having washing machines and driers? Who, exactly, is that going to liberate? How many hours of drudgery are you going to save every day by having that field induction charger?

Oh, that's right. None. A handful of seconds, at best. Probably 1% of the time it takes to put gas in a normal car. That's what you're going to save. While giving a giant "f%ck you" to our grid and the high cost of generating, distributing, and delivering power.

So no - THERE IS NO POSSIBLE COMPARISON between such appliances and what you ignoramuses are wanting to do with your field induction chargers. None at all. And the very notion that you think there is proves beyond the shadow of a doubt that you're hopelessly idiotic and really should be removed from the gene pool.

Any and all arguments in favor of field induction charging are *wrong* and there is no changing that irrefutable fact. So go f%ck yourselves.

Maybe I have an induction charger because I don't ever remember plugging it in, but maybe the "gas" I swear I fill up with is really energy water?

What ever you do, don't look at ICE or solar power. Those are nowhere near 90% efficiency....

A billion dollars a year is a pretty defensible number if you assumed a largescale market base for EVs and they were using field induction charging.

I showed a pretty reasonable calculation above that NYC alone might toss out $60 million a year on their own.

As for your rant about "I didn't know my car was electric"...WTF are you smoking? Demonstrate to me where I said it was.

As for the continuing use of retarded comparisons to other invalid analogs, like ICE or solar power not being efficient either...

Firstly, I'm not saying they are. Secondly, it's irrelevant. Field induction charging would be net-new to our society, it would waste massive amounts of energy from an already overtaxed grid, and provide ZERO benefit to society. And of course, the manufacturing and distribution network for gas/diesel is a different one from our electrical grid - we're not teetering our grid because an ICE car doesn't get mileage that's up to your "standards."

Saving 2 seconds because you didn't have to plug a cord in is not a benefit to society.

Irrelevant. The point is that people here are advocating throwing away massive amounts of power because they think a few seconds of their time is more important. It isn't. And besides, if these things are in parking lots where you drive to work, then the recharge is happening during the day.

The amount of time saved plugging an EV in vs. putting gas in an ICE car is almost infinite anyway. A few seconds vs. a few minutes.

Plug your car in. No social good is served by saving those few seconds, and the waste is a big social detriment - regardless of when it happens.

Totally agree.

The only legitimate use of these I can picture is ares where it's not feasible to run power lines and maintain traditional plug-in stations.

But for someone to use one of these in their own garage, when an outlet is 3 feet away? Disgustingly wasteful.

But this just goes to show what I've been saying and what we already know. People don't buy cars to "save the planet". Generally more selfish personal motives are in play.

This would be the equivalent of an ICE owner dumping ~15% of their tanks gasoline on the ground, just because they can. But because electricity is so cheap, and you don't pay for it on-use and are just billed monthly, there are idiots who think using wireless charging is okay.

It's like those hand-dryers in public restrooms. Think about how many of those damn things are in use in a typical city. It might surprise people to know I actually DO think about energy waste, but seriously. Those things waste a ton of power collectively all in the name of reducing paper use, which is 100% renewable!

Your example of hand dryers breaks here:

But how much money in energy does it take to recycle all those paper towels. How much does it cost to keep more janitors on staff to manage the waste and replenish the paper towel supplies? What about when this does not take place in time and the paper towels runs out (More than once I've dried my hands on my pants!). How much do all those paper towels cost - particularly when dang few people use only one (do you? I don't). How much does it cost to keep having plumbers come in to unplug the toilets because childish/stupid people try to flush paper towels either on purpose or in ignorance?

There is a lot of legitimate uses for inductive charging. I've provided several examples of possible benefits in this thread already. Not the least of which is that not everyone having and electric car will be parking it in their garage. I don't park my cars in my garage (there is too much crap in mine). My cars sit in the driveway with no power plugs anywhere near. If I had inductive charging, I can embed the charging pad in mty driveway and park right on top of it - never having to remember or worry about plugging in. Whatr about all the folks that lkive in high rise urban condos? A lot of those folks don't have a power plug anywhere near their parking slots. Mind, this might prove a problem regardless of how you want to charge your electric car, but it does open the possibility for the condo management garage builder to install sealed inductive pads in the asphalt of a percentage of these spaces when they are paving the parking garage.

Putting actual power plugs into the asphalt would be a little more prone to problems when damp cars park over them though there are ways to get around that too. I would just find having to use them a bother.

No, nobody is denying it's inefficient and stupid to use on a mass scale. We're saying regardless of how stupid the product is, the consumer has the right to decide what to buy. If we were to remove all the products that are dumb and/or harmful to society, we wouldn't have much of anything left.

Give this guy the prize. He hit upon the magic word here: CONVENIENCE.

There are hundreds of things that we all use every day that use energy at a horrendous rate that could be done using means that use little to no energy at all.

Why use a power drill when you can use a brace & bit? Why use a circular saw when you can use a hand saw. Why use a washing machine, clothes dryer, CAR? Each and every one of these things consume electricity or fossil fuels and have alternatives or that use no electricity of fossil fuels at all.

So why do they exist? macca007 knows why.

You have any proof of that? Because I highly doubt it's anywhere near that close.

Math posted on previous DT articles about field-induction chargers has shown that even in single city, millions of dollars a year would be wasted for electricity that was generated, transported, and then wasted by EV field-induction chargers.

That is the 2% he is talking about, but that's for phones. I'm not sure how different it is for higher power. I can't think it's THAT different, I'd assume more losses at higher power levels, but not insane amounts.

After reading a little bit more it seems like it's more a question of how quality are the components rather than physics.

Some wireless chargers will be good and some will be shit, there's not enough data to really compare yet.

I read the page and the wireless power link's transfer efficiency if 70% of copper wire. The 2% percent you think is the difference probably came from subtracting this 70% from efficiency of power adapter which is 72% and is same for wired and wireless charger.

I don't think you're reading that page correctly:
The transfer efficiency of the wireless power link is typically 70%.
It uses the 70% figure more than once, it one case using the phrase "up to," implying that this is a high-quality target that is often missed due to cost-cutting. Other sources I Googled up use "60% - 70%" as well.

Interestingly, one source I found claimed that resonance charging (induction charging's sister) is getting "80% - 90%" in the lab.

Total power consumption of two wired chargers: 2 * ( 2.8 + 2.8 ) = 11.2 Wh
Total power consumption of one wireless charger with two receivers: 7.9 + 2.8 = 10.7 Wh

You see that the total energy consumption is comparable. Although wireless transfer is obviously not as efficient as transport over a copper wire, wireless power transmitters saves standby power energy when the wireless transmitter replaces multiple external power adapters.

This comparison is for two mobile devices charging simultaneously on one wireless charger vs. two wired charging adapters. I don't find this comparison to be invalid, except that this use case is improbable, probably impossible, for the Bosch device in question. One for one, the wireless charger in this example is actually drawing twice the power.

I'm sorry there were individuals here complaining about power efficiency, when they don't actually know what they are saying.
Nearly everything you have does not have 100% or even 99% efficiency. A bridge rectifier, the old way of turning AC into DC outputs at 80%.
Unless you change everything to superconductors there is going to be power lost everywhere.
I don't know much about internal combustion engines but I would imagine a lot of the power is lost.

Get a 101% efficiency and you have invented something that never needs to be refueled. !!

A moot point when you're talking about choice. A charger loses power. Your only choice otherwise is to not use a rechargeable battery. But once you do get a rechargeable battery, you have the choice to lose 20% of the power or 44% (70% of 80%) of the power.

I won't argue that the choice is bad or not, or that convenience is or isn't better than resource conservation. But I will say that your argument -- that losing 44% of the power doesn't matter because we were losing 20% anyway -- is not a valid argument.

If wireless charging takes 10-20% hit in efficiency but greatly spread the use of EV then I would not hesitate to use it. Comparing that to how inefficient an ICE engine is along with its environmental concerns, it's not a hard choice.

Personally, the main reason I'll be getting an EV (the ~2015 "~$30k" Tesla, probably) is to save money on fueling. Tossing around 30% of the savings seems silly. I'll be plugging mine in. Let me know when the "90%" resonance charging gets out of the lab.

Various sources list the efficiency of the the power transfer to be a minimum of 90%. That is really good for an inductive interface across a minimum 6" gap.

So they basically lose about 10% efficiency compared to a direct plug in. Just being able to cut down on the wear of the plug in socket has to be worth some part of that 10%.

As far as overall efficiency of charging that depends on the voltages involved and the overall design of the charging system as well as the battery pack.

The most likely scenario I can think of is a business building a new parking lot, or sectioning off its existing one, and doing charging spaces as paid parking. Expensive, too! $10 probably, or more. Cheaper than filling up a gas tank though.

It's $3k now because of the development costs that has to be distributed between a small volume of units. I don't see why it can't be under $500 in the future and even more efficient.

I actually don't think this is too expensive for what it is and if I had an electric vehicle I would definitely save up for this. They should have come out with a version for the Tesla Model S first since 3k is less of a substantial amount for those owners.

It ends up being silly when you add the cost of this onto your electric car. You are already paying $8000+ premium over a like model petrol, then you add another $1000-3500 for a charger. Insane.

I hate electric vehicles and would not even consider owning one for the forseable future, however I don't care about the added cost it is just easier and it's for a car not my electric shaver I understand that it will cost more. Also it isn't adding the cost to the car really since you don't have to give it up when you give up your car and get a new one. There is also the resale value I am sure it wouldn't be hard to move at the right price.

I own a Chevy Volt and this doesn't really seem to be worth it. Besides on the Volt forgetting to plug in isn't a big deal since you have gas as a backup although yes, that's not as efficient and defeats the whole purpose of getting one!

If they could make it a lot cheaper that would help.

A better version of this technology could be if they could wirelessly electrify roads. Then you could get a charge by just driving around.

This should be included with the EV. Some serious concrete demo would be required to run the underground lines in conduit.

Either way this is the way to go for EV's.

If you can flatten these you can install a strip of these at intersections & in turn lanes. Plus of course parking spaces, at your office and so on.
